FASTENING DEVICE FOR SEATS.

SPECIFICATION forming part of Letters Patent No. 535,231, dated March 5, 1895.

I Application filed May 23, 1894. Serial No. 512,150. (No model.) I

To all whom it mag concern:

Be it known that 1, CHARLES G. TAYLOR, of Farmington, in the county of Whitman and State of Washington, have invented certain new and useful Improvements in Fastening Devices for Seats, of which the following is a full, clear, and exact description.

This invention is more particularly applicable to seats and chairs used in school houses, opera houses, railroad cars and other vehicles, or places in which the seat as a whole is required to be fastened down to the floor.

The object of the invention is to so fasten such and other like seats to their places that, while they will be firmly and steadily held thereto, they are readily removed when required to permit of cleaning the room or place they are in without interference by the seats, and the floor and other parts of the room thereby be more readily scrubbed or cleaned, and said seats be as easily replaced again in a brief period of time. In such seats or chairs the seat proper is usually mounted on bifurcated legs or supporting frames and my improved fastener is applied to these parts and made to readily engage with and disengage from fixed sockets or keepers on the floor by means of bolts, substantially as hereinafter described, said sockets or keepers only projecting a short distance above the floor so as to present but little or no obstruction to the cleaning of the floor when the 'seats or chairs are removed for the purpose.

Reference is to be had to the accompanying drawings, forminga part of this specification, in which similar letters of reference indicate corresponding parts in all the views.

Figure 1 represents an end elevation of an opera chair or other like chair or seat, with my invention applied and showing the chair as fastened to the floor, one-of the fixed sockets or keepers being shown in section, to illustrate the position of the bolts that engage said seat supporting frame with said, fixed socket or keeper. Fig. 2 is an inverted plan in partial section, of the whole chair or seat with its engaging and disengaging attachments applied. Fig. 3 is a view in perspective, looking from above, of one of the fixed sockets or keepers detached from the floor; and Fig. 4 is an inverted perspective view of one of the seat supporting frames or legs, in

part, with one of the locking bolts applied. Fig. 5 is a detail perspective.

A indicates the seat proper of the chair or of metal and is represented as consisting of back and front legs I) 1) connected by braces c c and provided with feet d d.

While I have shown the seat of the chair as being square in shape, it will be understood that it may be of any desired form, and the fastening devices be applied in an equally effective manner as to the square seat.

D indicates the floor of the room or place in which the chair is to be fastened.

Fixedly secured in or on the fioor D are bolt receiving sockets or keepers E, only projecting at their outer ends a slight distance above the floor. These sockets or keepers,

for each seat supporting frame B, are arranged.

at such distance apart one behind the other, as when the chair or seat is put in position, the feet d d enter snugly down within or between the raised outer ends of said keepers, that have bolt holes 6 e in them. Furthermore, the under surfaces of the feet 01 (Z are each provided with a longitudinal rib f that fits down within a groove g in the upper surface of the depressed portion of each keeper E. This rib and groove fit of said parts seats the legs B in proper position relatively to the boltholes e e and serves to hold the whole seat or chair from lateral shake. After the Whole seat or chair has been thus placed in its proper position, it is fastened down vertically and held from upward movement by rods or bolts h it being shot into the bolt holes e e in the keepers E. These bolts h h which are applied to each seat supporting frame or leg B, are freely connected with the opposite ends of a double crank or beam G centrally secured upon a vertical rock shaft H passing up through the braces c c and operated by a lever or handle I that when swung horizontally in the one direction causes the beam G to project the rods or bolts 71. it into the holes 6 e in the keepers E to fasten the chair down to the floor, and which when swung in the op posite direction draws back or liberates the bolts from the keepers, to allow of the removal of the seat or chair as and for the purposes hereinafter described. The lever or handle is provided at its inner edge with an upwardly projecting lip i which serves as a finger piece to enable the person to take hold 5 thereof, and the lip also engages the inner 10 claim as new and desire to secure by Letters Patent 1. The combination with the seat legs having front and rear feet at having fiat under sides and outer ends, said feet having lon- 15 gitudinally extending ribs f on their lower faces and transverse bolt apertures extending through them from front to rear, of the angular sockets or keepers E provided with transverse bolt apertures e in their upwardly ex- 20 tending faces, and having longitudinally extendinggrooves g in the upper sides of their depressed horizontal portions, and locking bolts extending through the feet apertures into the apertures e, substantially as described.

2. The combination with the seat legs having cross bars 0 cand angular transverse feet cl, and the angular transversely apertured sockets E receiving the feet between them, the adjacent flat faces of the feet and sockets being provided with longitudinally extending ribs and grooves respectively of the locking bolts sliding in the said feet apertures, and engaging the socket apertures, vertical rods mounted on the bars 0 c and provided at their lower ends with cross pieces to which the bolts are connected for simultaneous action, and provided at their upper ends with horizontally swinging operating handles I each having a lip i to engage the upper bar 0 substantially as described.

CHARLES G. TAYLOR.
